Dispositif (1) de séparation des constituants d'un milieu (M) fluide, comprenant un élément de séparation (3) de ces constituants, contribuant à délimiter, en amont et/ou en aval dudit élément de séparation (3), une enceinte fermée (2), à laquelle est raccordé au moins un conduit (C), caractérisé en ce que : - ledit conduit (C) comprend au moins un moyen d'obturation (5) activable, dont l'activation est apte à la fermeture et à l'ouverture au moins partielle dudit conduit (C); et en ce que - ledit dispositif (1) comprend des moyens de commande (7) de l'activation du ou desdits moyens d'obturation (5), aptes à commander la fermeture et l'ouverture, au moins partiellement, dudit conduit (C), de manière cyclique, selon une fréquence supérieure à 0,008 Hz.
摘要:
The invention relates to a star screen, in particular for a screen machine, the star screen (I) being designed substantially having a disc shape and capable of being disposed on a shaft, at least two star fingers (1 - 12) extending outward from the center point of the star screen. The invention is characterized in that the length of the star fingers is different.

A continuous belt drilling mud separation unit (10) is removably mounted in a box-like housing (30) disposed in the flow path of drilling mud or drilling fluids and is operated by a motor (40) on the housing (30). The separation unit (10) includes a generally rectangular frame (11, 12), a tensioning system (21, 22, 23, 24), and a wide continuous belt (17A, 17B, 17C or 17F) in the form of a mesh screen (17A), chain (17B), self-cleaning chain link belt (17C), or combination chain link belt and wire mesh screen (17F) extending around rollers (29A, 29B, 42A, 42B) or sprockets (16). Liquids and particles smaller than the openings in the belt pass through the openings and liquids and particles larger than the openings are transported on the moving belt and are discharged off of one end of the belt.

The bottom of the oscillating sieve can be composed of at least a cast, injection molded or vulcanised perforated plate, made of an elastic material, such as plastic or rubber. The bottom has a plurality of openings (5) and ribs (2, 3, 4) surrounding them, linked together in a single piece thus forming the perforated plate. Such a plate allows the self cleaning effect to be obtained, in an area of each opening (5), through a relative movement of the opening edges, so as to spread the self cleaning effect over the largest possible area of each opening (5). To this purpose, at least two ribs (2, 3, 4) surrounding the openings (5), have different flexion strenghes obtained through differenciated sections and/or through bracings (8).
摘要:
La présente invention est relative à des machines de criblage vibrant comprenant une grille (2) de criblage plane située dans un plan incliné d'un angle a non nul par rapport à l'horizontale, un dispositif d'alimentation en matériau à cribler positionné à l'extrémité haute de la grille, un générateur de vibrations agencé pour transmettre des vibrations à la grille, dans lesquelles la configuration spécifique des fils métalliques (5) constituant la grille permet un nettoyage aisé, en particulier lorsque les matériaux à cribler comportent des matières fibreuses. La présente invention est également relative à des grilles de criblage pour machines de criblage vibrant, à des installations de traitement de déchets comprenant de telles machines, et à des procédés de traitement de déchets mettant en oeuvre les dites machines.
摘要:
A cleaning device for a sewage screen is described. Said cleaning device comprises a suction head (3) which is guided across the screening surface of the sewage screen (2) by means of an adjusting mechanism (5). The suction head (3) is connected to a suction chamber, inside which a solid separator, e.g. in the form of a separation screen, is arranged and the sucked solids are separated from the water. In order to substantially maintain the negative pressure and simultaneously be able to empty the suction chamber, a weight-controlled water drainage flap is arranged on the bottom of the suction chamber and opens as soon as a certain water level has been reached in the suction chamber.
摘要:
An apparatus and method for separating solids from a solids laden drilling mud (14), the method comprising the steps of introducing solids laden drilling mud to a first side of a screen (13), the drilling mud passing through the screen (13) and screened drilling mud located the other side of the screen (13) characterised in that an oscillating tray (18) is located in the drilling mud and spaced from the screen, the oscillating tray imparting motion to the drilling mud to facilitate screening of said solids laden drilling mud in the screen (13).
摘要:
The invention concerns an assistance device for screening and declogging the screen cloth of a screen comprising a vibrating structure and in contact with the screen cloth by a wave generator, in particular ultrasound waves. Said structure consists of a part (4) having a cross-section with an inverted L-shape with a base (5) and a shoulder (6); said base (5) lower surface (8) is connected to the generator (7) and at least the shoulder end and preferably the upper surface (9) including the shoulder (6) is in integral contact with the cloth (3). The vibrating part can comprise two shoulders, in integral contact with the cloth overlapping on either side of the base.
